Farrah Abraham is severing all ties with her fellow Teen Mom OG costars.

The 26-year-old reality star called Catelynn Baltierra, Maci Bookout and Amber Portwood “trash moms” on Tuesday in a tweet that also slammed MTV.

“Watching @TeenMom @mtv I’m so happy I don’t welcome anymore of @MTV made up s— to help mention the other trash moms feel important lmao good luck @MTV #2018goals #Sorrynotsorry,” she tweeted, while also including a gif of herself laughing.

Abraham’s costars were not immediately available for comment.

This isn’t the first time Abraham has been involved in feuds with her costars.

During the season 6 reunion of Teen Mom OG, Abraham verbally attacked Portwood and her then-fiancé Matt Baier about their age difference.

Portwood stormed onstage and attempted to swing at Abraham but was pulled off by security — not before yelling at her, “Watch your f—— mouth!”

Abraham filed a cease and desist against Portwood for alleged harassment, PEOPLE confirmed in June 2017. Abraham’s lawyer alleged Portwood had “been making false and defamatory statements about Ms. Abraham to the media.”

The mother of one accused Catelynn’s husband, Tyler Baltierra, of being gay in December. She tweeted, “Tyler’s gays still doesn’t admit it.”

Baltierra shares 2-year-old daughter Nova with wife Catelynn (they’re also biological parents of daughter Carly, 8, whom they placed for adoption after she was born, as broadcast on MTV’s 16 and Pregnant.) Baltierra wasn’t fazed, tweeting, “In order for her to really insult me, I would first need to value her opinion and the lion does not dwell on the opinions of sheep.”
